Hepsia Advanced Features
The Advanced tab provides you with quick access to an array of advanced features, among them the Memcached distributed memory caching system and the Varnish Cache web accelerator, which will help you optimize your web sites and applications without having to log out of the web hosting Control Panel. Depending on the website hosting package, these features are either included by default or are available in the form of easy-to-get upgrades. InnoDB and NodeJS support is available as well.
Varnish Cache is a web accelerator also popular as a caching HTTP reverse proxy. You can install it in front of any server that speaks HTTP and configure it to cache the content. Varnish Cache is very, very fast and will improve the loading speed of your site. One of the chief virtues of Varnish Cache is the flexibility of its configuration language, VCL, which permits you to specify how incoming requests should be dealt with.
Memcached is a generic distributed memory caching system for increasing the loading speed of dynamic database-powered sites. It is used to lower the number of times an external data source (such as a database or API) is read by caching data and objects in RAM. The Memcached system uses a two-tier architecture. The Memcached memory object caching system is employed by some of the most traffic-intensive sites on the World Wide Web and is supported by famous CMSs like Joomla and WordPress.
InnoDB is the default database engine for the MySQL open-source relational database management system. A storage engine is the principal software component that a database management system uses to create, retrieve, update and delete data from a database. The latest version of InnoDB offers serious improvements in efficiency, security and functionality. InnoDB offers the standard ACID database transaction features, along with foreign key support. InnoDB is included by default in most binary distributions from MySQL AB.
